Using the broad replicating range JHJ-3 phage replicon, a shuttle vector for Escherichia coli and actinomycetes has been constructed. The vector, pOJ31, bears the lacZ alpha fragment allowing a blue/white gene cloning system. pOJ31 also contains a polylinker of 15 unique cloning sites and the phage T7 promoter. The vector has been used to stably express the mel gene from plasmid pIJ702 in Streptomyces lividans.
利用具有广泛复制范围的JHJ - 3噬菌体复制子,构建了一种用于大肠杆菌和放线菌的穿梭载体。该载体pOJ31带有lacZα片段,可实现蓝/白基因克隆系统。pOJ31还包含一个具有15个独特克隆位点的多克隆位点和噬菌体T7启动子。该载体已用于在变铅青链霉菌中稳定表达来自质粒pIJ702的mel基因。
